The Vacheron Constantin Patrimony Reference 4667 from the 1950s is a definitive mid-century dress watch, celebrated for its ultra-thin profile and minimalist design philosophy.

• Case Dimensions: 32mm diameter (though often misquoted as 35mm due to its wide-wearing thin bezel). It features a slender profile of approximately 7mm to 7.5mm in thickness. 

• Case Material: Cast in solid 18k Gold (most frequently yellow gold, though rare rose/pink gold variants exist). 

• Μηχανισμός: The legendary Caliber 1001 manual-winding mechanical lever movement. Introduced in 1951 and based on a Jaeger-LeCoultre ebauche, this 18-jewel movement is prized by collectors for its stunning finger bridges and incredibly thin 2.94mm architecture.

• Dial Configuration: A signature mid-century Champagne / Golden dial layout often featuring a clean layout with small seconds at 6 o'clock. The hour markers are typically delicate lines or onyx-inlaid indexes paired with thin baton hands.
